Advances in microelectronics and integrated circuits, system-on-chip design, wireless communication and intelligent low-power sensors have empowered the development of Wireless Body Area Network (WBAN). IEEE 802.15.6 standard, approved in 2012, targets at wireless body area network. The network simulator 2 (NS-2) is a popular and powerful simulation tool, which provides substantial support for simulation...
Given the growing concern over energy consumption and associated global warming, green communication is becoming more and more important. Lots of efforts have been put into investigating energy efficiency based design in wireless systems. Unfortunately, the maximum energy efficiency of a point-to-point link is normally achieved when the transmit power approaches zero, which, however, is not desirable...
Using multiple paths to transmit data simultaneously in wireless sensor networks is regarded to reduce end-to-end delay and achieve higher throughput. However, the interference between these multiple paths causes a significant reduction in the overall performance. Previous methods tried to solve this problem either with the aid of special hardware or under unrealistic assumption, such as the interference...
This paper considers the problem of link scheduling with non-preemptive constraint in wireless mesh networks. In real-world implementation, there is often a constraint that a link can only transmit once and occupy consecutive time slots during a frame. We refer to it as the non-preemptive constraint. To date, only few scheduling algorithms in the literature has taken such constraint into consideration...
